Commercial sealant contractors near Newtown

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Commercial sealant contractors in Newtown, done properly

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Newtown, phone 01277 525 020 or email drawings and photos with the site addresses. We work on window and door perimeters, external facade joints and floor and threshold joints, and the usual reasons a site gets in touch are expansion joints with the sealant torn out and gaps behind commercial kitchen worktops and sinks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Newtown it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Multi-site clients with buildings in and around Newtown can put several sites on one programme, so standards and paperwork match across every site.

Around smaller places such as Newtown, small firms often work from converted barns, yards and rural units. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What about asbestos in old mastic?

It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Can you handle sealant work across several sites?

Yes. We regularly take on multi-site work and planned maintenance programmes.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

After the work

For the best life from the joints:

  • Add sealant to the planned maintenance inspection list
  • Deal with small splits before they become leaks
  • Have extract fans checked so wet areas dry out
  • Make sure contractors see the asbestos survey before cutting out old mastic

Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Location, for remote and island sites
  • The site’s rules and procedures
  • Quantities, in metres or numbers
  • How accessible the joints are

Pricing sealant joints depends on how many there are, their condition and the access. Call for a quote.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings
  • The postcode of the building
  • How the joints are reached, and at what height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or use the quote form.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If neighbouring businesses or buildings around Newtown need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we will need
  • Arrange parking or a loading space

Why it’s worth doing now in Newtown

On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings, and they’re where most failures begin. It shows over the following seasons rather than at handover. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
